sweet85's clutch issue's

[sweet85]

So I installed a new clutch yesterday and when I went to pull it out of the garage it would not go into gear. It has peddle pressure, fluid is full, slave cylinder pushes the clutch fork fine. For some reason the the clutch fork must not be putting enough pressure on the pressure plate! I've done one before and this is very weird.

[79coyotefrg]

what kind of a clutch??  have you checked the adjustment?? make the slave to fork rod as long as possible

[sweet85]

Its a perfection from Advance Auto. The one I took out was surely the original. It was rusted to heck. I just put the slave on a few weeks ago and its not adjustable. It looks like its fulling extending. That is so weird. Is there any other adjustments?

[KDXSR5]

This may sound dumb, but did you put the clutch disc in backwards? My friend did it on his truck and the clutch doesn't work too well that way.

[sweet85]

Trust me, at this point nothing realy sounds dumb. I had a buddy helping because he has done one also and he actually lined it and I torqued em up. That was this first thing that I asked him. Did you face the disc the right way? He said yes

[kneedownnate]

did you put the clutch disc in backward

  my thoughts too...

[jimbo74]

have you bled the clutch and adjusted the pedal freeplay and height?



here is something i screwed up when doing mine... there is a hole in the clutch fork.... i thought the hole was for the piston of the slave... i couldnt get my slave to bolt on.. that hole was for a return spring and the piston went in a little nub next to it.... haha, when the piston sits in the little nub.... it bolted up just fine

[Tallchevy]

Did you have the flywheel resurfaced? Is the flywheel within spec's for thickness?

[sweet85]

The fly wheel is fine. I havnt adjusted the clutch pedal but I dont think that it will do much. when I press in the clutch the slave seems to extend fully and press on the pressure plate like normal. Now, for what ever reason there isn't enough pressure on the pressure plate because the fly wheel wont stop spinning to put the truck into gear.

[Tallchevy]

That's because the flywheel only stops when you shut off the engine. When you push on the clutch pedal your disengage the input shaft to the transmission & the transmission stops turning.

Sounds like either the disc is in backwards or maybe you should try and bleed the slave cylinder just to be sure. Maybe i missed it, but how old are your clutch MC and slave? no leaks I'll assume?

[toyotanner]

adjust the pedal.... or the disc is on backwards.

[sweet85]

slave and master is new. Everything is new. Line is bled and the slave pushes on the fork fine. Disc must be on backwards. That is all there is left.

[jimbo74]

[Tallchevy]

Did you bench bleed the master cylinder before installing it? If not, take it off & put it in a vice & bleed it.

[KDXSR5]

Did you bench bleed the master cylinder before installing it? If not, take it off & put it in a vice & bleed it.

I have been told this is not necessary, and when I put my new master, slave, and lines in I did not bench bleed it. I guess it is worth a shot though... better than either pulling the engine or dropping the transmission to see if the disc is backwards.

[jimbo74]

you bleed it to get out reapped air that might then accumulate in the lines and cause a proble,.... their might be some air in the lines, but unless it's completely dry, his clutch ain't right... and that needs to be addressed.....

[sweet85]

When I watch the slave push on the clutch fork it fully extends so I know my lines are fine. I was just told last night by a family friend who is a mechanic said that if the disc is on backwards it will not work. So, either the throw out bearing came off which is highly unlikely. It has two clips holding it on but would obviously not give you pressure on the pressure plate if it did come off. Or the disc is on backwards. You never know, the little print that says this side facing the fly wheel could be printed on the wrong side. The only way to find out is to tear it open again, unfortunately!!!

[jimbo74]

well, you can use a flashlight and look through the shift fork hole to see the bearing, without dropping hte tranny, but... i think your disk is on backwards.....

someone else correct me if i am wrong, but i am pretty sure the fat side if the disk goes to the pressure plate

[jimbo74]

hope this helps

[KDXSR5]

Wow I just put my new Marlin 1600 clutch in a couple nights ago... I sure am happy i put it in the right way! Thanks for the drawing jimbo

[Toymin8r]

Shouldn't have to bleed the clutch if it was engageing and disengaging ok before you replaced it unless you let air into the system.  I've replaced several clutches, the latest being Dirtoyboy's a few months ago and never had to bleed the system nor adjust the pedal.  Either you put the disc in backwards  or you didn't get the fork mounted on the throw out bearing correctly.   You can peel back the boot on the fork to check it but you have to do it all over again if you put the disc in backwards.

[sweet85]

Thanks everyone for the insight on this subject. I will be sure to let everyone know what the issue was.

[sweet85]

So I'm beyond frustrated. I just dropped the tranny and check the clutch. It was on correctly along with the throw out bearing. I put it all back together in record time. NO joke, it only took me 3 hrs to drop and bolt everything back. With a friend helping of course. However, it still does not releasing. In others words I still cannot get the truck into gear. I even replaced the slave cylinder even though it was new also and that still didn't work. And I adjusted the linkage on the pedal/master cylinder. Everything is new except the clutch master cylinder. But its not leaking and it I get good pressure. Fork moves fine. Could the clutch be bad??? Please help!!!! This has gotten to be rediculous. 

[joey0712]

Are you SURE u have the disk in the rite way and not backwards???

[sweet85]

Positive! That was the only thing that I thought it could be and sure enough it was on right. It sucks because for this first time I think I'm going to have to take it to a shop for something that only took me 3 hrs. And there going to look at there little handy book and see how long it is suppossed to take and charge me $100 an hr. No telling what it will cost.

[Toymin8r]

Will the truck go into gear when the engine isn't running?    Drop the tranny again and manually push in the pressure plate by hand with the throwout bearing and see if the clutch disc moves freely.

As far as taking it to a shop,  I'm not tryin to tell you what to do but there are only a few things that could possibly be causing your problem.

[sweet85]

Yeah, the truck goes in and out of gear fine when its not running. Everything worked fine until I went to change it out. There is markings on the pressure plate from the through out bearing but its like its not getting enough pressure for some reason because the fly wheel still spins!! I dont want to take it to a shop either but I have had it apart twice.
Checked everything ,bled everything and adjusted everything. I dont now what else to do but take it apart again and try a different clutch even though this one is new.

[Toymin8r]

The flywheel will always spin because its bolted to the crakshaft.  So will the pressure plate.  The clutch disc itself is splined and is what gets freed up when pushing the clutch in.   I don't really know what else to tell you to try other than another clutch and pressure plate.   If you didn't do anything to the hydraulic system while installing the new clutch then it should have to be touched.   

Another thought would be to check for obstructions on the springs on the pressure plate.   I had a truck once that the bushings on the clutch disc brok off and wedged themselves in the pressure plate springs and wouldn;t allow the clutch to release.

[sweet85]

One thing that I didnt do is when I took off the new clutch to check it out, was slide it over the shaft coming out of the tranny to make sure the splines match up.
